摘要：

During a site investigation at Gouderak, The Netherlands, the observation was made that groundwater tides in several piezometers near the shallow tidal river Hollandsche [Jsse] were running ahead of the river tide by more than an hour. Although the current theory of groundwater flow does not account for this effect, the phenomenon can be explained by means of well-known elementary mechanisms. The superposition principle is adopted to derive formulae for the phase shift and the attenuation in case of a single aquifer covered by an aquitard. It is shown that for this simple system the maximum negative phase shift at the river bank amounts to 1 4π radians (corresponding to 1 1 2 hour for the semidiurnal tidal component). © 1987.
